| Name | Data Type | Value |
| Region | boolean | |
| Description | string | This property is used by a provider to define whether or not the client can specify start and end disk sectors for the region. |
| ModelCorrespondence | string | CIM_DiskDriveDiagnosticSettingData.LBAStart, CIM_DiskDriveDiagnosticSettingData.LBAEnd |
| Seed | boolean | |
| Description | string | This property is used by a provider to define whether or not the client can specify the seed for the tests that generate a random number sequence for testing. |
| ModelCorrespondence | string | CIM_DiskDriveDiagnosticSettingData.Seed |
| DataPatterns | string[] | |
| Description | string | This array property is used by a provider to define the list of data patterns supported by the test. A data pattern is a string interpreted as a 16-digit hex value. For example, a data pattern of all ones would be FFFFFFFFFFFFFFFF while alternating ones and zeros would be 5555555555555555 or AAAAAAAAAAAAAAAA . The pattern will be repeated as necessary to fill the specified data buffer. |
| ModelCorrespondence | string | CIM_DiskDriveDiagnosticSettingData.DataPatterns |
| DataSizes | uint64[] | |
| Description | string | This array property is used by a provider to define the list of data sizes supported by the test. |
